is it possible to convert to fuel injection?

Question

i have a 1985 kawasaki GPz550a2. is it possible to convert a carburated bike, to fuel injected ?

Answer 1

I wouldn't bother to try unless you could obtain the entire fuel and electronic system from an injected GPz 1000, '79 Classic or 6 cylinder Voyager. While state of the art at the time, those systems are rather archaic compared to current systems. You'd need to devise a good way to mount the engine temperature sensor to the cylinder block because Kawasaki made a block with a mounting point especially for that purpose. The air temp sensor wouldn't be a problem but you'd need the throttle bodies with the throttle position sensor as well as the DFI box, an expensive item. You'd have to make alterations to reduce the fuel flow and have a return line and check valve brazed into your fuel tank. The earlier versions used an air flow sensor in the air filter housing which could be problematic to make fit yours. It could be done, but in my opinion, it would be mighty hard to get it to run right and there would be little to gain from it. No power gains and the only advantage would be not needing to use the choke when cold. If you have carb problems, clean and or overhaul them and you'll be better off.

Answer 2

I imagine it might be, but is likely to be more expensive and difficult that the results would justify to be honest. Try doing some googling; other people must have had the same idea.
